I have a hen who is about a year old. Her crop is not wanting to empty as it should. It feels kind of doughy and I can also feel food stuck in it. I don't think it's sour. She is still pooping normally. I've been feeding her soft mushy foods to keep her from getting malnourished. They seem to be digesting okay but I can't get rid of that doughy mass. I've tried withholding food and giving her vegetable oil as well as a lot of water. She only eats after giving her some water to loosen the mass. She is also not drinking water on her own. I've been giving her water myself throughout the day to keep her hydrated. It's been several days and nothing's helping. Is there anything else I can try? I've seen a recipe for breaking apart doughy crops but it uses baking soda and that concerns me a little since birds can't burp.
